How to Fix Your Computer Issue When it’s not Working

If your computer are not working the we are giving here step by step solution to make working your computer

My computer does not turn on” … PC, notebook not working

Do not panic that your computer will not turn on. The problem may be serious, but there are more possibilities to solve it yourself. Let’s see why a PC or notebook does not turn on and how to fix it.

Check the power supply

This is one of the most common problems on notebooks. There are a number of reasons, from the wrong laptop power supply to the plug fuse being disconnected.

If the power supply is not a problem, first make sure the battery is charged. I’m not sure, but the battery itself has no power indicator. Remove the remaining power completely and use the power charger immediately.

Check the redundancy

The charger is the reason why the notebook is not turned on. Many notebooks use the same size plug, especially if they are the same manufacturer. If you own more than one laptop, it is often the case that you use a plug in the wrong power supply. Let’s make sure these power supplies are not providing different voltages or sufficient power.

Other devices, such as battery-powered speakers, may use the same. Generally, notebooks use the same voltage of 16 ~ 20V.

Check the second plug fuse. Remove a good fuse and use a screwdriver.

If you have an extra power cable to connect to the power supply, you can test for a fuse more quickly.

If the power supply is OK, it is time to check the wires. Especially, the tip where the plug connecting the notebook and the black brick meet is the weakest part. If the black outer protective sheath is peeled off and you can see the wire color inside, it’s time to buy a new power supply.

Even in the case of a PC, a power supply can cause problems. However, few people have the extra to install and test it. So check first the plug fuse. To check if the fuse inside the power supply is faulty, you must first remove it from your PC case.

One of the most common PC power supply problems is that the PC turns off unexpectedly rather than never booting. If there is an LED showing that the power is on, you can check that the power button is properly connected and working via the LED.

Check the screen

If your notebook does not stop booting Windows, disconnect the external display, including the projector and the monitor.

The computer’s power LED turns on and you can hear the hard disk or fan spinning. If no image appears on the screen, darken the room and check for a very faint image on the screen.

It is easy to think that the notebook does not boot because the screen is not visible. If there is a faint image of the Windows login screen, it is probably that the screen inverter has failed. This component changes the current required for the screen to AC, changing the DC from the battery or power supply described above.

Replacing an inverter is not difficult if you have a driver. However, it is important to purchase the correct replacement part. Interburs are not cheap, so you may not have the economic margin.

If the notebook boots but the image does not appear at all, the LCD panel may be wrong. It is possible to replace the laptop screen, but it is quite difficult. And switching screens is costly. Older laptops may be better off buying new ones.

In the case of a PC, there is not much that can be done to resolve a broken monitor. But the check is simple. To find out why your PC is not booting, try replacing the power lead with a video cable or a full monitor.

Removing a USB drive or memory card

If you think that everything is OK with the power supply and screen, disconnect the USB drive or memory card before turning on Windows.

There is a good reason to separate them. In general, if you get an “Operating system not found” error message, it may be the USB port or the USB drive or memory card inserted in the card reader.

In most cases, this means that the BIOS is configured to try booting from a removable storage drive before the internal hard drive for a quick boot. If this is the case, check the DVD or Blu-ray drive for possible disk failure.

Try recovery discs

If you get any other error messages, or if your card, external drive, or disc did not cause the problem, try using the recovery disc.

If you have a recovery disc, you can use the Windows DVD, otherwise you can download the recovery disc image (using another computer, of course), burn the CD or DVD, or unzip it to a USB flash drive. You can then try to boot up and try to fix the problem on Windows.

If the virus was the cause of the problem, you can use a recovery disk from an antivirus vendor to detect and remove malware.

Be the boot into safe mode

If you cannot boot into Windows, it may not be available in safe mode. You can boot into safe mode by pressing the F8 key at startup. The notebook provides a menu that allows you to boot in safe modes, such as F8.

If you can enter safe mode, you may be able to figure out why your laptop or PC is not booting. In safe mode, you can remove recently installed programs, remove recently updated drivers, or create new user accounts if your account is compromised.

Faulty or incompatible hardware

If you install some new memory or other hardware, it may interfere with booting.

Reinstall the old memory and try again, if necessary If the LED reading shows the POST code on the motherboard, you can search the manual or online for what that code means.

Booting a newly assembled PC can be tricky. The best tip is to disconnect all but the least necessary to boot into the BIOS. The minimum components of a PC are as follows.

Motherboard

CPU with heat sink

Graphics card (plug-in graphics card can be removed if motherboard has graphics card)

One memory (removes others and leaves only one slot 0 or manual recommended)

Power supplies

Monitors

All other hardware is unnecessary. Hard drives, optical drives, and other components are not required. Here are some common reasons why a newly assembled PC will not boot.

If the power cord is connected incorrectly: The motherboard has a separate 12V socket near the CPU

Make sure that the mains board is properly connected to the additional 24VDC ATX connector and the attached power supply.

If the component is not installed or not properly seated: Check that the pins are not bent over the CPU and CPU socket, remove the memory, graphics card, and CPU and reinstall them.

The motherboard power button is connected incorrectly.

If the power cable is not connected to the graphics card: If you need a GPU, make sure the PCI-E power lead is connected.

If you connect the hard drive to the wrong SATA port: Make sure that the primary drive is connected to the SATA port powered by the motherboard chipset.

One of the reasons why a PC cannot boot is a hardware error, which is not easy to solve. Hard drive problems are fairly common. If you hear periodic clicks or repeatedly make a lot of drive turns and occasionally lose power, this is a sign that it will soon fail.

In some cases, the drive is removed and left in the freezer for several hours. But this is usually only a temporary solution. You should quickly back up or copy all the files to the second drive. If the hard drive does not turn on again, it is time to start a new hard drive. I just want to back up important files recently. Hopefully your computer not working will be worked now.
